These plates of the hind-body are on the upper side soft, being protected by the wings covering them. It is along the margins of the upper side under cover of the first pair of wings that the spiracles, or breathing holes, are situate. The two pairs of wings differ in character, for whilst the second pair are of thin, semitransparent material, strengthened by longitudinal ribs, or " nervures," and adapted for flying, the first pair are thick and homy, and from their shape unsuited for flight. They have been adapted for nse as covers to the second pair, and in flight are merely lifted up to give freedom of movement to the effective pair. When the beetle is not engaged in flight, the At all points the beetle is protected by this armour, the limbs and external organs being attached by hinge-like joints that allow great freedom of movement without providing weak places for the attacks of enemies. Taking a large species, such as the stag-beetle, for the better elucidation of its external form, we find the trunk exhibiting three clear divisions such as we know to be characteristic of Insect structure ; but in this case »i have to be careful or we may be deceived by what we see. As a matter of fact, the rearmost of the three divisions of the upper side of a beetle does not coincide with the hind-body, but includes also a large part of the fore-body. The latter, as in all Insects, has to support the legs and
